FREDERICK W. CAPPELEN, 0F MINNEAPOLIS, MINNESOTA, ASSIGNOR TO DECARIE HOPKINS, MINNESOTA,

A CORPORATION OF MIN- :INGINERATOR.

To all whom it may concern I Be it known that I, Fimosmcn W. Carrnnnn, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Incinerators, of which the following is a specification The object of my invention is to provide an incinerator'havmg an improved form of grate which Will allow the flames to circulate around the mass of garbage on the grate and will also prevent the load on the grate from clogging and choking up the middle portion of the rate.

A further ob ect is to enlarge the surface exposed to the action of the flames.

The invention consists generally in a grate having a centrally arranged header, and grate bars or tubes depending therefrom and diverging outwardly to the walls of the combustion chamber.

Further the invention consists in upright bars or tubes connecting the diverging bars with the top of the combustion chamber and spaced from the side walls thereof.

In the accompanying drawings forming part of this specification, Figure 1 is a vertical sectional view of an incinerator embodying my invention, Fig. 2 is a vertical sectional view taken on a section line at right angles substantially to the section line of Fig. 1, Fig. 3 is a vertical sectional view through thepaper burning chamber of the incinerator.

In the drawing, 2 represents the combushaving a grate 3, a water space 4 in its Walls, and with a chamber 5 forming the top of said combustion chamber. A hopper opening 6 is provided through the top of the combustion chamber having covers 7 flush with the floor 8, and beneath the covers are doors 9, which swing downward under the Weight of the material deposited therein. A space 10 is provided beneath the floor 8, extending over and around the top of the combustion chamber. A flue opening 11 is formed in the wall of the combustion chamber leadin to a chamber 12 wherein a Wall 13 of firebrick is provided, the brick being so arranged that passages. will be formed between them through which the products of combustion will pass to the stack. The brick will become incandescent and will consume a large' proportion of the gases in the prod- Specification of Letters Iatent. Application filed. March 2 1, 1911.

opening and being carried into the chamber at tions 17 which extend outwardly, parallel, to

substantially, with the grate 3 and communicating with the water space in the walls of the combustion chamber. Pipes 18 connect the outer ends of the horizontal portions 17 with the chamber 5 erably substantially parallel of the combustion chamber a sufiicient distance culation of sides of the that the flames can ass between this material and the walls a? the combustion chamher and assist materially in drying the mass on the grate rendering its combustion more with the walls and are spaced therefrom to allow cir-. the hot air and gases on both rapid and complete. The centrally arranged header will have the efiect of separating the; material as it falls from the hopper and-v prevent it from accumulating and packing down in the middle of the grate. Furthermore, this header horizontal portions of the grate, the flames will pass between the divergingportions of the bars 17 and will expose a greater portion of the material to the action of the flames than would be zontal portions extended entirely ac'r'Gs's the combustion chamber. In other words, the raised central portion of the grate has the effect of separating the material and throwing it out toward the sides'of the combus- 100 g tion chamber and thereby hastening the drying and insurlng a more rapid combustionof the material. Contact of the material with the walls of the combustion chamber is prevented by the upright pipes 18. The 105 water circulating through the' header 15 and the tubes leading therefrom will become heated and the steam'from the chamber 5 nets of combustion. Pipes 1% connect the 55 the water space a a centrahposi ot andare pref- 76 garbage supporting grate, so so being raised above the possible if the horimay be drawn off for commercial purposes through a means which I have not thought necessary to illustrate herein.

The paper combustion chamber forms the subject-matter of a separate application Serial No 616,764, filed March 2-1, 1911, and need not be referred to except to state that it consists of a chamber 19 having a cover 20, a fuel grate 21, a paper supporting grate 22 and an opening 23 leading to the chamber 2. A fuel opening 24 is also provided in the Wall between the chambers 52 and 19 oni'a level substantially with the grates and opposite the stoking hole 25. A similar stoking hole 26 is preferably provided opposite the grate 22.

I claim as my invention 1. The combination, in an incinerator with a combustion chamber formed with a water space in its walls, of a header consisting of a pipe communicating at its ends with the water space in the opposite walls of the combusm'on chamber, tubular grate bars extending outwardly from said header and communicating with said water space, and means preventing contact of the material with the walls of said chamber.

2. The combination, in an incinerator having a fuel grate and a filling opening, of a grate for the refuse material havin substantially horizontal side portions an a raised central portion, said raised central portion T dividing the material deposited through said filling opening and directing it upon said side portions, and means preventing contact of the material with the wallsbf said incinerator. I

3. The combination, in an "incinerator, with a combustion chamber, having water spaces in its walls of a fuel grate and a filling 0 ening, a garbage grate arranged above said uel grate and consisting ofa' centrally arranged header, tubular grate bars extendoutwardly therefrom and forming a circu sting means betweensaid water spaces and sald header and vertical tubes connecting the outer portions of said outwardly extending tubular grate bars with the top of said combustion chamber, and preventing contact of the material with the walls of said combustion chamber.

4. The combination, in an incinerator with a combustion chamber having a fuel grate and a filling opening and a water space, of a garbage grate arranged above said uel grate and comprising a water circulating header extending across said combustlon chamber,

.water circulating tubes extendingfrom said header to said water space, a portion of said tubes preventing contact of the. material with the walls of said chamber.

5. The combination, in an'incinerator hav-. ing a fue1 grate and a filling opening and circulating chambers, of a header extending across the combu'stionchamber of said incinerator beneath said filling opening and having. its ends communicating with said circulating chambers, pipes depending from said header and having outwardly extend ing, horizontal portions also communicating with circulating chambers in the walls of. said incinerator, said header operating to divide the material falling thereon and direct it outwardly upon the horizontal portions of said pipes and means preventing the material falling on the horizontal portions of said pipes from contacting with the walls of said incinerator. V

6. The combination, in an incinerator with a combustion chamber formed with a circulating space in its walls and a grate provided in the lower'portion of said chamber, of a header comprising a pipe arranged midway substantially of said combustion cham ber above said grate and having its ends communicating with the circulating chamher in the walls of said incinerator, tubular grate bars having their inner ends connected to said header and depending therefrom, the middle and outer portions of said tubular grate bars being horizontal, substantially,

and communicating with the circulating space In the walls of said incinerator above a combustion chamber havingwater spaces in its walls, of a header centrally arranged in said combustion-chamber and communieating at its ends with the water space in the opposite walls thereof, tubular grate bars extending from said header to the Water space on opposite sides thereof, andcirculating tubes connected to the upper portion of said combustion chamber and communieating with said tubular grate bars and preventing the contact of the material with the walls of said chamber.

8. The combination, in an incinerator having a combustion chamber, of-an incinerat.-- ing grate comprising a centrally arranged header, water-circulating tubes extending from said header, said header being raised above the level of the outer portion of saidtubes to direct the material outwardly to-. ward the walls of said combustion chamber, and means preventing contact of the material with the walls of saidchambeng 9. The combination, in an incinerator with a fire-grate and a combustion chamber formed with a water space in its Walls, of a header comprising .a said combustion chamer below the middle portion of said chamber adjacent to said firegrate and comm ani ca-tingat its endswith ipe extending-across burs bein inwardlv turned and communieating with said header, the outer portions of said burs presenting substantially fiat surfaces on each side of said header upon which the material is directed by said header and the upwardly urned inner ends of said bars, substantially as described.

In witness whereof, I have hereunto set my hand this 9 day of March 1911.
